Eight-claw executing mechanism applied to weed-eradicating robot

Abstract

The invention relates to the field of agricultural robots, in particular to an eight-claw actuating mechanism for a weeding robot, which comprises a shell, a rail changing sliding block system, a main shaft turntable system, and eight sets of stick bite shaft systems, wherein the stick bite shaft system rotates along with the main shaft turntable system, and the rail changing sliding block overcomes a compression spring and is lift up under the action of an upward external force so as to connect an upper side rail and a lower side rail. Every time one set of the stick bite shaft system rotates to one side of a plant row, the shaft system drives a rotating shaft to move downwards under the action of the rail pressure, and rotates under the limiting actions of a sleeve guide rail and a limit pin which are connected with the turntable system simultaneously, so that the stick bite externally extends into in-row plants to finish weeding motions. The eight-claw actuating mechanism has the advantages of controlling a plurality of sets of the stick bites to extend to the outside to perform plant inter-row weeding simultaneously and ensuring the coverage factor of inter-plant intervals. Besides, the eight-claw actuating mechanism has the advantages of continuous weeding motions, simple and flexible operation, and convenience for the weeding robot control and manipulate.

Description

technical field

[0001] The invention relates to the field of agricultural robots, in particular to an eight-claw actuator applied to a weeding robot. Background technique

[0002] In order to get rid of the heavy manual labor of weeding in the field and overcome the harm caused by chemical weeding methods, mechanized and intelligent weeding is called the direction of plant protection development. Among them, the removal of weeds between the plants in the row must be completed by an intelligent weeding robot. The weeding mechanisms seen at present, such as the rakes of companies such as Einbock Lely Rabe werk, the rotary weeder of Bezzerides company, the rotary hoe of Yetter company, the Danish spike weeder of Kongskilde company, etc., are all designed for mechanized weeding between rows, and cannot Used for weeding between plants in the row. A few devices that face in-row weeding, such as Buddingh's tilt-to-rotating disc finger weeding mechanism, are only used in the seedl...
